Nord Express by Cassandre, 1927

The "Nord Express" (Northern Express) was a train service introduced in 1896 by Compagnie Internationale des Wagons-Lits, a Belgian night train company. It left Paris and traveled via Brussels, Cologne, Hanover, Berlin, Konigsberg (now Kaliningrad) and Dvinsk (now Daugavpils) to Saint Petersburg.
After World War I the train was diverted to Warsaw instead of Saint Petersburg. It departed daily from Paris and Ostende, traveling to Berlin and from there - to Warsaw and in 1936-1939 - also to Moscow, three times a week. After World War II the "iron curtain" and air travel brought the end to this famous train.
